The latest trailer for Pokemon Omega Ruby and Alpha Sapphire comes packed with a ton of new details about the Ruby and Sapphire remakes.

The trailer reveals three new Mega Evolutions, including Mega Altaria, Salamence and Lopunny. Mega Altaria will be a Dragon/Fairy type where Salamence and Lopunny will maintain their Dragon and Normal type after Mega Evolving.

Contests will be returning in Omega Ruby and Alpha Sapphire, and the Mega Evolution mechanic will play into them if you manage to impress the crowd enough.

Hordes, battles against groups of wild Pokemon at once, will be migrating from Pokemon X and Y into Omega Ruby and Alpha Sapphire.

Nintendo also announced that players who get either game on launch day, November 21st, will be able to acquire a Shiny Beldum, holding a Metagross Mega Stone through an in-game event.

Pokemon Omega Ruby and Alpha Sapphire were announced earlier this year. Nintendo recently confirmed that Secret Bases would be returning to the remakes after having been absent from the series since the original Ruby and Sapphire.
